~".j .i The present invention generally relates to apparatus for removing compressed snow or compacted ice (referred to hereinafter as compressed snow) from a road.
Various arrangements have been proposed for removing compressed snow or the like as referred to above. By way of one example, there has been disclosed in Japanese ' Utility Model Laid-Open Publication Jikkaisho No.
62-114920, removing apparatus that includes a plurality of line cutting teeth provided on the undersurface of a ;~ chassis of a vehicle in a direction parallel to the advancing direction thereof, and a blade disposed behind said cutting teeth, whereby cut lines or grooves are formed in the compressed snow by the teeth. Thereafter, ;~ ~ 15 the compressed snow thus treated is separated by the blade.
In this known arrangement, however, there has been the problem that, since the underfaces of the teeth contact the surface of the paved road, both the pavement and the ., teeth are damaged.
To solve this problem it may be so arranged that the lines or grooves are formed in the compressed snow while the cutting means are kept out of contact with the surface of the paved road. For actual applications the following methods may be considered.

The present inventors carried out experiments for thawing ice employing heated air at 7Q0C, steam at 120C, and a heating medium at 120C, with findings as shown in Fig. 10, in which curves (1) and (2) respectively represent the results obtained by blowing hot air or steam from above the ice, while curve (3) denotes the result when a blade through which a heating medium is circulated is brought ; into pressure contact with the ice.
As seen from Fig. 10, for forming grooves of 20 mm ~i, 10 depth in the surface of ice more than 30 seconds are '.,t required for curve (1), 3 to 4 seconds for curve (2), and 6 to 7 seconds for curve (3), and thus, in curves (2) and (3), the processing speeds were almost the same as those of the conventional arrangements.
An essential object of the present invention is to provide apparatus for removing compressed snow from a road which apparatus avoids damaging the surface of the road, and yet is capable of removing the compressed snow in an efficient manner.
~i 20 Another object of the present invention is to provide i,. such apparatus that is simple in construction and stable in operation with high reliability, and can be readily manufactured at low cost.
To these ends, the invention provides removal apparatus for compressed snow comprising a steam cutter pcovided with a plurality of longitudinally extending pipes connected to ; a header, said pipes having steam discharge means formed in undersurfaces thereof, and blade means for scooping up compressed snow located behind said cutter, the angle of said blade means being adjustable in relation to the direction of travel of said apparatus.

to enable a heating medium at high temperature to circulate therethrough, and blade means for scooping up compressed , :
snow located behind said cutter, the angle of said blade means being adjustable in relation to the direction of travel of the apparatus.
There is shown in Fig. 1, a removing apparatus for compressed snow according to a preferred embodiment of the present invention, which generally includes a steam cutter 10 having a plurality of steam pipes 12a (Fig. 3) and a removal blade 20. In this embodiment, the apparatus is shown mounted at the front of a motor vehicle 1.
The vehicle 1 is provided on its chassis B with a ~:, boiler 2, a fuel tank 3, and a frame 4 extending forwardly and provided at its front end with front wheels 6 operated lS by a handle 5. Rear wheels 7 are provided below the chassis B in the known manner.
; The steam cutter 10 further includes a steam header 11, the plurality of steam pipes 12a branching from this header 11 and being disposed in a parallel relation with each other in the travelling (longitudinal) direction of the vehicle 1. A skirt portion 14 surrounds an elongated opening 13 or a plurality of nozzles n each formed on the underface of a steam pipe 12a.
The group 12 of steam pipes 12a is suspended from the frame 4 and can be raised or lowered, for example by a pair of hydraulic cylinders 16 connected to respective sides of the cutter 10.
~' The steam header 11 is connected to the boiler 2 through piping 17, so as to supply steam at 120C to the steam pipes 12a for discharging such steam onto the compressed snow through the discharge ports lS defined by 'l the skirt portions 14, whereby to form a plurality of $~ straight grooves G in the snow Sa ~Fig. 71.
As shown in Fig. 6, the blade 20 includes a main body 21 and a steam edge 22 attached to the lower end of the ., .~
. . .
,:, ., . . . .
. . . . :

body 21. Steam is supplied into a passage 23 in said edge 22 through piping now shown so as to be discharged forwardly after having heated the edge 22. As shown in Fig. 7, the blade 20 can be arranged to be adjustable in S its angle to the direction a of travel by means not shown.
In this apparatus, when the vehicle 1 is driven in the direction a in Fig. 7 while steam is being fed to the steam header 11 from the boiler 2, the steam is discharged onto compressed snow S on the surface of the pavement R (paved road) (Fig. 6) through the discharge ports 15 to form the straight grooves G as described earlier.
The compressed snow thus formed with the grooves G is scooped up by the steam heated edge 22 of the blade 20 as also shown in Fig. 6, so that sections Sa of the compressed snow a~e broken into pieces to be pushed to the side.
When the vehicle 1 is to be moved to a fresh working ~.
; site the steam cutter 10 and the blade 20 are raised to an ~ upper location in the vehicle.
; Figs. 8 and 9 show a modification of the apparatus described with reference to Figs. 1 to 7.
$; In the modified apparatus, the cutter 10 is replaced by a heating medium circulation cutter 30 including hollow heating medium blades 31 for circulating the heating medium therethrough, whereby to form the grooves G by causing such . 2S blades 31 to contact the compressed snow S under pressure.
More specifically, respective ends of the plurality of blades 31 are connected to headers 33a and 33b through pipes 32a and 32b, as shown in Figs. 8 and 9. The boiler 2 is replaced by a heating medium circulation boiler 34 designed to feed the heating medium at high temperature (120C) to the header 33a, the other header 33b being connected to the boiler 34 for return flow.
~` Other aspects and functions of the modified apparatus of Figs. 8 and 9 are similar to those of the first embodiment.

- 6 - Z~R88fi As is clear from the foregoing description, since the formation of grooves in the compressed snow is effected by spraying of steam or by pressure contact of heated blades ~ therewith, no damage is inflicted to the surface of a ii' 5 paved road.
Moreover, during the formation of the grooves, heat is also conducted to the paved surface, which helps to reduce adhesion between the undersurface of the compressed snow and the paved surface, thus facilitating subsequent separation of the compressed snow by the blade.
Furthermore, according to the first embodiment, since the sprayed steam is restricted by the skirt portions and , is not directed sideways, the thawing of the compressed snow is effected at a very high thermal efficiency.
It is to be noted here that, when a steam heated edge is attached to the blade so as to be both heated and to ; discharge the steam towards its front lower portion, the separation of the compressed snow by the blade can be more 'j readily effected.
It should also be noted here that, although the apparatus is shown at the front of the vehicle, the concept . ,~
of the present invention is not limited to this arrange-ment. For example, the snow removal apparatus can be arranged to be towed by the motor vehicle.
Although the present invention has been fully described by way of example with reference to the accompanying : drawings, it is to be noted here that various changes and modifications will be apparent to those skilled in the art.
Therefore, unless otherwise such changes and modifications depart fro~ the scope of the present invention, they should be construed as included therein.
